According to the brochures (links here
), the electric awning package and entry door awning that were standard on the 2006 39K became optional on the 2007 39K.
If you call Winnebago customer support, with your coach's serial number (or VIN) in hand, they should be able to send you a copy of the coach's build sheet. That will show you what options were installed.
The wiring diagram (link here
), sheet 6, zone A-4, shows the connector that feeds the awning motors. If you can get to the connector, it should reveal whether or not it's wired and powered for the awnings.
